HOG-OILER.

Application filed March 1, 1916. Serial No. 81,352.

To aZZ whom it may concern:

Be it known that I, HARLEY S. BUsBY, a citizen of the United States of America, and resident of Washington, county of Washington, State of Iowa, have invented a certain new and useful Improvement in Hog-Oilers, of which the following is a specification.

This invention relates to that type of hog oiler in which is provided an oil-holding tank adapted to be anchored securely to the ground or floor and in which a rotary oilapplying member is mounted in such manner that its rounded oil-applying surface shall overhang the upper edges of the trough to enable it, as it is turned by the animal, to transfer oil or other liquid in the troughspace from the tank or trough to the animal, as is well known. The object of the present invention is to provide an inexpensive, simple and reliable apparatus of this type, as more fully hereinafter set forth.

In the drawing annexed- Figure 1 is a vertical sectional view, partly in elevation, of a preferred embodiment of my apparatus;

Fig. 2 is a vertical sectional view on a line at right angles to the line on which Fig. 1 is taken; and

Figs. 3 and 4. detail views hereinafter set forth.

Referring to the drawing by reference characters, 5 designates a metal cup-shaped tank which, as usual, is provided with a base plate 6 so constructed as to enable it to be properly anchored to a floor or wooden baseframe. At diametrically opposite points, the tank 5 is provided with upwardly-extending trunnion supports 7 each of which is provided on its inner face with an upwardly-opening notch 8 for the reception and retention of one of the trunnions 9 of a ball 10.

The ball 10 is hollow and its diameter is such that when mounted on its trunnions it dips about one-third of its diameter into the tank, so that at the point of its largest diameter it projects outwardly over the upper edges of the tank, to thereby facilitate access by the animal to the rubbing surface of the ball. The ball is made in two hemispherical sections clamped together, with their meeting edges in contact, by a bolt or rivet 11 extending centrally through the ball and the opposite trunnions 9, the heads of this bolt or rivet being counter-sunk in the trunnions.

Specification of Letters Patent.

Patented Feb. 25, 1919.

The ball is provided with an annular series of perforations 12 located about midway between the trunnions, so that the oil in the tank may flow into the interior of the ball and thus utilize a part of the interior of the ball to increase to maximum the oilholding capacity of the tank. These perforations 12 are formed by making corresponding notches in the abutting edges of the two hemispherical shells, so that when the shells are clamped together by the rod or bolt 11 a line of holes will be formed around the ball at the line of jointure of the shells.

Projecting inwardly into each of the trunnion notches 9 is a lug 13 which has a downwardly-facing shoulder and an upwardly and outwardly-inclined inner face. These lugs, when the ball is in place, engage over the trunnion flange and thus lock the ball against upward displacement. One or both of the trunnion supports 7 are cast sufliciently thin and light to be capable of springing outwardly far enough to disengage one or both the lugs 13 from the trunnions, thereby permitting the ball to be lifted out of the trunnions. it is simply necessary to force it downwardly until one or both of the trunnion arms 7 spring outwardly far enough to permit the trunnions to snap past the lugs, the inclined faces of the lugs serving as cams.

To automatically drain off or expel any water that accumulates in the tank 5, I cast, integral with the tank and directly under one of the trunnions, a water passage 14, this passage being in the form of a tube or conduit on the exterior of the tank. The lower end of this conduit opens at 15 into the tank near the bottom thereof, and at its upper end it is provided with an overflow 16 whose overflow. edge is located on a level a little below the lowest part of the edges 12 of the tank. The water, being heavier than the oil, will sink to the bottom of the tank and will be, as is obvious, forced out through opening 15 and up through the passage 14 and will overflow at the opening 16 and thereby automatically drain practically all the water from the tank without loss of oil. By locating the water drain at one side, just under one of the trunnions, it will be seen that it is out of the way and will, therefore, ofier no obstruction to the animals in gaining direct access to the rotatable member.

In placing the ball in the trunnions,

Having thus described my invention, what I claim is: I v

In a device of the class set forth, a tank having upstanding trunnion supports at diametrically opposite points, a rotatable member having hollow trunnionsjournaled in the upper ends of said supports, and inwardly-extending lugs on the supports engaging in the hollow trunnions, one at least of the trunnion-supports being capable of being sprung outwardly far enough to disengage one of the lugs from its trunnion to Copies of this patent may be'obtained for 24th day of February,

five cents thereby permit the rotatable member to be readily locked to thetrunnion supports or to be removed therefrom, said lugs having 15 downwardly-facing shoulders and upwardly and outwardly-inclining inner faces, for the purpose set forth. I
